Chronic paronychia is an inflammatory disorder of the nail folds of a toe or finger presenting as redness, tenderness, and swelling.
The cuticle and nail folds together constitute the three-sided protection of skin around the free edge (nail tip) of the nail plate.
Nail abnormalities are common, affecting the shape, thickness, or color of the nails.
Nail-fold swelling and large pus-filled lesions are typical of a bacterial paronychia
Nail discoloration, in which the nails appear white, yellow, or green, can result from different infections and conditions of the skin.
